Water Temperature: Daily Trends, Historical Records, and Forecast

⚠️ As of today, the minimum water temperature ranges from 54°F (12°C) to 60°F (15°C). The water is significantly warmer, and swimming becomes possible for most people. However, caution may still be required for prolonged stays in the water, as extended exposure can cause discomfort. This is a suitable temperature range for short swims and for those accustomed to cooler water. For more comfortable swimming, it is recommended to use proper gear. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** Forecast - Our water temperature forecast

Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.

Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

The Monongahela River, located in the northeastern United States, flows through the state of Pennsylvania and is known for its role in the region's industrial and cultural history. The water temperature in the Monongahela River varies throughout the year. During the colder months, particularly in late fall and winter, the water temperature can drop significantly, often ranging between 30°F and 40°F (1°C to 4°C), making swimming unadvisable due to the cold and potential safety hazards. As the weather warms in spring and summer, the water temperature typically rises, reaching around 70°F to 80°F (21°C to 27°C) during the hottest months, which can make swimming more comfortable.

Swimming in the Monongahela River is generally not as popular as other forms of recreation such as boating or fishing, largely due to the river's strong currents and industrial history. However, there are areas with calmer stretches of water where swimming might be more feasible, particularly in the summer when the water temperature is more inviting. That said, caution is always advised, as the river can have varying water levels and swift currents, which may pose risks to swimmers. Public access points along the river provide opportunities for water activities like kayaking and canoeing, and although swimming is not the main draw, the river's scenic views and recreational facilities make it a popular spot for outdoor enthusiasts. As with any waterway, it's important to check for safety advisories before entering the river.
